## why the weight unit of badminton racquet is 'U' but no others? what U stands for?

why the weight unit of badminton racquet is 'U' but no others? what U stands for?

why the weight unit of badminton racquet is "U",what U stands for?
There is a history both in material and in weight about that, known to all, using carbon graphite to make badminton racquet is one milestone in about 1969s,and the other milestone is in the weight,that successfully lighten the weight of badminton racquet to 100gram,before that,tempo of game is so slow for the racquet is heavy(about 130gram or more),for the technological skill improved,racquet weight can be controled to 100gram,whice is the other milestone.
U stands for "Under 100gram",how many U stands for how many gram under 100gram.1U =5gram,(people can feel difference obviously 5gram weight increment or unweight)
so 3U is 3*5gram=15grams less than 100gram, that is why 3U=85g-89g.

Thnx vm. Absolutely no idea except for their respective equivalents in terms of grams. I understand there was also a different weighing unit when it was above 100 grams back then? All in all, it is enlightening to know.

Now they just need to standardize the grip system. It can be confusing that a Victor G2 = Yonex G5.

5. ## What the "U" stands for?

.
Glad that this information confirms/verifies (what the "U" stands for) as was posted by Winex West Can in this thread (The "U", the "G" and the "tension" specifications of a Badminton racket), located at;

In general, Winex designates its weight categories as follows: 2U = 90-95g; 3U = 85-89g; 4U = 81-84g; and 5U = 75-80g.

6. The weights over 100 g are suffixed by "L" - wonder what that stands for? Lard-arse?

How about heavier than 200 gms? If there ever was one training racquet heavier than 200 gms? Still suffixed by L?

You are funny, thnx anyhow. Shouldn't squash racquets be next in line from baddy racquets BEFORE tennis racquets? So L is it?

10. A 200 g badminton racket should carry "WTF", IMO.

With the right balance, a 200 grams badminton racket is essentially a training racket!!!

I would guess that L = Loaded (heavy), or perhaps Learner.

...given it some thought as to why it is suffixed L as we've already learned as to why the U suffix.

Maybe, just maybe, the wooden even the steel or a combo of wooden and steel racquets back then did weight over 200 grams at some point. Then, came the racquets that weighs in just under 150 grams, therefore the L suffix which can be attributed to light. Thereafter, the under 100 grams which the OP stated is suffixed with U (under 100 grams). But the suffix U may also meant ultra-light under Yonex specifications?

14. Knowingly or not L for Light (115g.) is actually correct . 2L = LL = extra light (< 110g.) and 3L = extra extra light (< 105g.)
U was introduced with the Cab8 as the first racket Under 100g.

According to a racket history lesson on a dutch badzine which I'm sure was taken from the official catalogues, prints, booklets or whatever existed at the time ...

A very interesting read that unfortunately auto translates quite poorly . Interesting tidbits: Blacken is older than the wooden Cab3, Cab7 = Blacken with graphite encased steel shaft.
